The Formation of the First Quasars. I. The Black Hole Seeds, Accretion and Feedback Models
Qirong Zhu, Yuexing Li, Yiting Li +4
Supermassive black holes (SMBHs) of are generally believed to be the central engines of the luminous quasars observed at , but their astrophysical…
Deep Learning of Diffuse Optical Tomography based on Time-Domain Radiative Transfer Equation
Yu-ichi Takamizu, Masayuki Umemura, Hidenobu Yajima +2
Near infrared diffuse optical tomography (DOT) provides an imaging modality for the oxygenation of tissue. In this paper, we propose a novel machine learning algorithm based on tim…
FIR-luminous [CII] emitters in the ALMA-SCUBA-2 COSMOS survey (AS2COSMOS): The nature of submillimeter galaxies in a 10 comoving Mpc-scale structure at z~4.6
Ikki Mitsuhashi, Yuichi Matsuda, Ian Smail +20
We report the discovery of a 10 comoving Mpc-scale structure traced by massive submillimeter galaxies (SMGs) at z~4.6. These galaxies are selected from an emission line search of A…
FOREVER22: galaxy formation in protocluster regions
Hidenobu Yajima, Makito Abe, Sadegh Khochfar +14
We present results from a new cosmological hydrodynamics simulation campaign of protocluster (PC) regions, FOREVER22: FORmation and EVolution of galaxies in Extremely-overdense Reg…
The CO universe: Modelling CO emission and H abundance in cosmological galaxy formation simulations
Shigeki Inoue, Naoki Yoshida, Hidenobu Yajima
We devise a physical model of formation and distribution of molecular gas clouds in galaxies. We use the model to predict the intensities of rotational transition lines of carbon m…
High circular polarization of near infrared light induced by micron-size dust grains
Hajime Fukushima, Hidenobu Yajima, Masayuki Umemura
We explore the induction of circular polarization (CP) of near-infrared light in star-forming regions using three-dimensional radiative transfer calculations. The simulations trace…
Star cluster formation and cloud dispersal by radiative feedback: dependence on metallicity and compactness
Hajime Fukushima, Hidenobu Yajima, Kazuyuki Sugimura +3
We study star cluster formation in various environments with different metallicities and column densities by performing a suite of three-dimensional radiation hydrodynamics simulat…
ART: A 3D Parallel Multi-wavelength Radiative Transfer Code for Continuum and Atomic and Molecular Lines
Yuexing Li, Ming F. Gu, Hidenobu Yajima +2
ART is a 3D multi-wavelength Monte Carlo radiative transfer (RT) code that couples continuum and emission lines to track the propagation of photons and their interactions with…
Starbursting [O III] emitters and quiescent [C II] emitters in the reionization era
Shohei Arata, Hidenobu Yajima, Kentaro Nagamine +2
Recent observations have successfully detected [O III] and [C II] lines from galaxies in the early Universe with the Atacama Large Millimeter Arr…
